Selenia Dimensions/3Dimensions DICOM Conformance Statement for AWM Introduction


2.0 Introduction Hologic, Inc. develops and markets a full line of mammography products including the family of Selenia Dimensions full-field digital mammography systems with the Hologic 3D Mammography option and their Acquisition Workstations. The Advanced Workflow Manager (AWM) enhances the workflow between multiple Acquisition Workstations within a local area network that are configured within an Advanced Workflow Manager cluster.

2.1 Audience This document contains the DICOM conformance claim for the Advanced Workflow Manager. This document is intended to aid in connecting the Advanced Workflow Manager to other components that make use of the DICOM standard for interconnecting networked imaging devices.

The information within this document applies to Advanced Workflow Manager Software version 1.10. The reader of this document should be familiar with the DICOM standard and PACS components that utilize the standard.

2.2 Remarks A DICOM conformance statement, the structure and content of which are stipulated by the DICOM standard, is intended to aid in determining the suitability of interconnecting digital imaging devices. References to specific functionality in a conformance statement are not sufficient to guarantee interoperability between components. The following should be considered when evaluating interoperability:

• The Advanced Workflow Manager conformance statement provides a starting point for ascertaining whether the product can communicate with other systems.

• The only way to know for certain whether the Advanced Workflow Manager can interoperate with other systems is to perform connectivity testing.

• This document represents a best effort to document the functionality of commercial versions of the Advanced Workflow Manager and is not a functional specification of any Hologic component or product. Hologic reserves the right to make changes at any time to the functionality of the DICOM components described herein, and is committed to following the evolution of the DICOM standard.

3.0 Networking 3.1 Implementation Model

3.1.1 Application Data Flow

• The Retrieve Client Application Entity retrieves images. “Retrieve Images” is performed

upon the Advanced Workflow Manager receiving a DICOM conformant Grayscale Softcopy Presentation State object whose Study Instance UID is not in the Advanced Workflow Manager database. The Retrieve Client requests a remote AE for the corresponding study making the objects of the study accessible to Acquisition Workstations within the Advanced Workflow Manager cluster.

• The Storage Server Application Entity receives echo requests, images, and/or GSPS objects from a remote AE. The Storage Server Application Entity is available whenever the Advanced Workflow Manager application is running.

• The Verification Client Application Entity sends an echo request to a remote AE. The Verification Client Application Entity is available as part of the Advanced Workflow Manager Service Tool utility.

3.1.2 Functional Definition of AE’s Multiple local Application Entities may be active simultaneously.

3.1.2.1 Functional Definition of Retrieve Client Application Entity The Retrieve Client AE is activated when the Advanced Workflow Manager receives a Grayscale Softcopy Presentation State object whose Study Instance UID is not in its database. An association request is sent to the remote AE and upon successful negotiation, a retrieve request is sent to the remote AE. The Storage Server AE is active whenever the application is running and will receive the study. If an association cannot be opened or retrieve request fails, an error is generated and the retrieve job is deleted.

3.1.2.2 Functional Definition of Storage Server Application Entity The Storage Server AE is active (i.e., listen port is active) to accept echo and storage requests whenever the Advanced Workflow Manager application is running. The received Instances are stored to a temporary directory and then imported to the database.

3.1.2.3 Functional Definition of Verification Client Application Entity The Verification Client AE is available to the user as a DICOM troubleshooting tool in the Service Tool utility. It is available to test all remote SCP devices.

3.1.3 Sequencing of Real World Activities The Advanced Workflow Manager (AWM) enhances workflow among Acquisition Workstations within its local area network cluster by tracking and providing access to received images and related information to all Acquisition Workstations within a cluster.

The AWM will also retrieve a study from a remote AE upon receiving a Grayscale Softcopy Presentation State object whose Study Instance UID is not in the AWM database.

In cases where error(s) occur during transmission, the affected job(s) will be retried if the error condition is temporary; otherwise it will be stopped.

3.2.1.3.1.1 Description and Sequencing of Activities The Retrieve Client attempts to establish an association with a remote Retrieve AE upon receiving a Grayscale Softcopy Presentation State object whose Study Instance UID is not in its database. A C-MOVE is requested to a remote Retrieve AE. The Retrieve Client releases the association after receiving the final C-MOVE response from the remote Retrieve AE.

3.2.2.4 Association Acceptance Policy When the Storage Server AE accepts an association, it will respond to storage and echo requests.

3.2.2.4.1 Activity – Receive Images

3.2.2.4.1.1 Description and Sequencing of Activities The Storage Server AE starts upon launching the AWM application. The Storage Server AE stores images and GSPS objects that are received so they can be made available to Acquisition Workstations within the AWM cluster. When the AWM application receives a request to shutdown, the Storage Server AE stops running after the configurable time (in seconds) assigned to the Shutdown Wait Seconds parameter has elapsed. As a default, if a received Instance is a duplicate of an existing stored Instance, the received Instance is ignored, and the AWM sends a status of storage success in the C-STORE-RSP. However, the Storage Server AE can be configured to delete the first imported Instance of a stored object and import the duplicate Instance of the stored object.



3.2.2.4.1.2 Accepted Presentation Contexts The Storage Server accepts associations using the following presentation contexts. Note: Implicit VR Little Endian is the Transfer Syntax AWM will accept as a default when more than one transfer syntax is proposed within a presentation context.

5.0 Support of Character Sets The Advanced Workflow Manager supports the following character sets for the values of Data Elements with a VR of SH, LO, ST, PN or LT:

• Default: ISO-IR 6 • Latin Alphabet No. 1: ISO-IR 100

6.0 Security The Advanced Workflow Manager does not support any specific DICOM security measures.

It is assumed that the AWM is used within a secured environment. It is assumed that a secured environment includes at a minimum:

• Firewall or router protections to ensure that only approved external hosts have network access to the AWM.

• Firewall or router protections to ensure that the AWM only has network access to approved external hosts and services.

• Any communication with external hosts and services outside the locally secured environment use appropriate secure network channels (e.g. such as a Virtual Private Network (VPN)).

• Other network security procedures such as automated intrusion detection may be appropriate in some environments. Additional security features may be established by the local security policy and are beyond the scope of this conformance statement.
